DC Marriot Marquis Convention Center Hotel

Challenges Solved

The ultra modern, 14-story Marriot Marquis DC hotel is located on a triangular site adjacent to three existing structures, including the historic Plumber’s Union building that was incorporated into the hotel.

MRCE provided innovative geotechnical foundation engineering service, including the design of a seven-level basement constructed by the "Top-Down Method." The excavation was 94 feet deep below ground, nearly equal to the height of the building.
